Answer:

[tex]Amount = 9.6km[/tex]

Explanation:

Given

[tex]Length = 0.7km[/tex]

[tex]Width = 0.5km[/tex]

[tex]Wires = 4[/tex]

Required

Determine the length of wire needed

First, we calculate the perimeter of the land.

[tex]Perimeter = 2*(Length + Width)[/tex]

[tex]Perimeter = 2*(0.7km + 0.5km)[/tex]

[tex]Perimeter = 2*(1.2km)[/tex]

[tex]Perimeter = 2.4km[/tex]

That is the amount needed for 1 row of wire.

For 4 rows, it would be:

[tex]Amount = 4 * Perimeter[/tex]

[tex]Amount = 4 * 2.4km[/tex]

[tex]Amount = 9.6km[/tex]
